Iterate forward and then reverse over STL container?

I think a more elegant approach would to treat the operation as a transaction. In other words, create a replacement copy of the accounts, and overwrite the original on success.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
